Timewarp Editor
Timewarp Editor
The Timewarp Editor allows you to modify the play speed and direction of video clips.
You can control speed and direction changes dynamically with Key Frames.
The Timewarp Editor is a clip effect; it has no effect on audio clips. Timewarp effects are rendered.
For basic information on video effects, see
“Effect Editors (Basics)” on page 11-62 and “Key
Frames”
on page 11-73.
Even though we may sometimes refer to “slower” and “faster” playback in order to clarify
a concept, the play speed of digital video is constant, depending on the system (NTSC: 30
or 29.97 frames/s, PAL: 25 frames/s). The illusion of “slower” or “faster” playback is cre-
ated when additional frames are interpolated (computed) or frames are omitted.
